Myinvention relatesto snow plowsland more particularly to snow plowsofthe type adapted to be propelled by a tractor or motor truck. e y

Heretoforeit has been well knownto provide snow plows mounted onorconnected to a frameadapted to .be secured to a motor truck axle in suchafmanner as 'to enable the truck to push the plow ahead of it., It isalso well known to mount or secure a plow in association with a Yframeadapted to receive a tractor and connected to the tractor in such amanner as to enable the tractor to propel the plow. Y

Structures such as those .indicated have proved to be of great advantagein clearing snow from highways and city streets and they arevextensively used in those cities and sections of the countrywhich aresubject "to substantial snow fallsl As a result ofthe extensive use ofsuch plows, however, various defects havebe'en observed and variousmodiiications made to correct them.' However, it may be observed thatsuch plows, land more particularly the V type plow, are frequentlydamaged yby obstructions as, for example, ice, and are relativelyineiiicient in snow of substantial depth due to the fact that they arepositively propelled by the truck or tractorto which they are attached.j j j j I Nowit is .the .obj-ect of my. inventionto provide a snow plowof the type indicated, which will be propelled through the medium ofresilient means, thus 'enablingvthe plow to more eectively act in heavyorjdecp snow andat'the same time avoid injury on'the striking of anobstruction'. Further objects of my invention are to provide a novel andhighly effective and vdurable structure and at.

the same time a structure ot'simplicity and economy in manufacture.

Having now indicated, in a general way,

the nature and purpose of my invention,v l

f will proceed to adetailed description thereof with reference to theaccompanying drawinffs in which there is illustrated a preferred :D s In embodiment and in which Figue l, iS 2L Plan vewof a snow Plow of 'theV type embodying my invention.

Figure 2, is a side view of the plow shown in Figure vl partly brokenaway to show details of construction.

Figure 3,'is a .view from the rear and partly in section, oftheplowishowninlligures Y, In: the lseveral figures the plow is formed by`a pair ot angular extending blades', a internally braced by means of aramefcom- Y posed of angle members @extending transversely between theVblad-es adjacent their rear ends, vertical angle members 0, to whichthe cross'lmembers are secured, and angle members d, secured together atthe front of thefplow and to the upper cross member I),

through plates e. A barf-extends fromthe v bers'j cross bracedadjacenttheir Vends ,by

memberslais adapted to be pivotally secured to a suitable fittingmounted on the front axle of' amotor truck, indicated by line Zv between.wheels mi, or to thefront of a frame such as is usually utilized inconnection with tractor propelled plows;

On the bar f are mounted alppair of spaced *A guides n and l0, Ainwhichv is adapted to slide one end of a rod p upon the other end ofwhich isV positioned a heavy, coil spring g. The spring isretained onthe rodvunder tension between a washer y which bears against` the guideol and a `washer ,1' which bears against a collar s secured to the'pin.

Secured tothe rod p is a bracket 4ton the top of which is provided ajournal for a pin u whichV extends therethrough and "through the ends ofthefframe side members j.

A' rod o extends vertically through the cross members band through a`slot fwV in a plate w secured to the frame members j. The :rod ismaintained inplace by pins ,2. l

It will now be observed t-hatif the frame members y' be connected topropelling means as a motor truck or tractor, and it will be understoodthat for the purposes of my in j vention a motor truckor tractor areequivalent, that the plow will'be propelled through the medium of thespring g, which acts be.

tween the rod p, which vthroughthe bracket t and pin u is secured totheframe members.v j, and the bracket o which is mounted on thel n n nuapex ot' ,theV plow.

bar f secured to the plow. The rod o as will be observed preventslateralmovementv of the plow.` It will be also observed that the rod p isturnable in guides n ando thus permittingfthe plow to retain a levelirrespective ot the frame members j, and since the pin uis turnable inthejournal in bracket t, the nose Aof lthe plow may liit to clearordinary obstructions'.

It will be noted that due to the propulsion of the plow through themedium of the spring g shock on the plow and propelling ineansissubstantially reduced and that due to t-he substantiallyuniversalconnection between trame members and the bar f the f tio theother ends ot the horizontal bars, up-

per and lowerv cross bars. connected to the lVertical bars, and allongitudinal bar connected to the center of the lower crossba'r andtothe two lower horizontal bars at the 2. `A snowplow of the V type-liavin'g two blades connected to each other at the apex y Vot' theplow, a supporting frame comprising an'upper anda lower set ofhorizontal bars connected to the blades,jthe bars et each set lbeingconnected to each other at one end at the apex` ofthe plow, verticalbars connected to the other ends ot" the horizontal bars, cross upper,and lower bars connected to the-'Vertical bars', a longitudinally,extending'bar connected to thelower cross bar and the apex of thedblades, and means. on said l'ongitiidinally extending bar forresiliently connecting a plow pushingfelernent thereto.

' 3; A snow plow of the Vtype having two blades connected to eachotherat tl'ie apex oi the plow, a supporting' frame comprising an'upper andalower set ot horizontal bars connected to. the blades, `the bars ot'each set being 'connected to each otherat `one end at the apex ot theplow, vertical bars connected to the other endel of thev horizontalbars, upper and lower cross bars` connected to the Vertical bars, alongitudinally extending vbar connectedto the lower cross bar and theapex of the blades, a runner connected to the longitudinally extending`bar, a shoe connected to each end of the lower cross bar,

and resilient means on said longitudinally extending .bar for connectinga plow` pushing element thereto.

Ll. A snow plow ot the V type having tw@ bars, and a pushing elementpivotallyk cona nected to the plow between the apex thereof and thevertical rod, said pushing element extending to the rear ot the plow andhaving a guide slot therein engaging said vertical rod. l

y 5. A snow plow of the V type having two blades connected to each otherat the`V apex ot' Vthe plow, bracing ktor the blades including upperandlower erossbars connected to the rear ends of the blades', a verticalrod connected to the central portion ot the .cross bars, andauyieldingpushing elenientpivotally connected to the plow between tht-apex thereofand the vertical rod, said pushing element extending to the rear oftheplow and having a guide slot therein engaging said vertical rod.

6. `A snow plow of the V type having two blades `connected to each otherat the apex of the plow, bracing for the blades-including upper andlower cross'bars connected to l the rear ends of the lblades, a verticalrod connected to the central portion oit the cross barsya' longitudinalconnected to the apex of the plow and' the lower Across bar, ahorizontal rod mounted for recipiocatfion in two guides connected tothe" longitudinal bar, a pusher pivotally connected to the horizontalrod between the guides, a' coinpression spring on thehorizontal rodarranged to be con'ipressed' by the pusher and the load on the'plow, andguiding 'i'neans oil the pusher engaging the vertical rod.

In testimony/'of which intention, l llave hereunto set my hand, atKennett Square, Pa., on this ninth-day of March, 1926.
